I didn't get to read the patch throughly yet but I am really confused by
this statement. The api is mprotect based which makes it ineherently
PAGE_SIZE granular. How do you want to achieve cache line granularity
with this API?

And I would really vote for simplicity first... Subpage granularity
sounds way too tricky...
